Multiple pyrene modified RNA duplex exhibits pyrene excimer fluorescence. The pyrene excimer fluorescence is significantly enhanced with an increase in the number of incorporated pyrenes. The pyrenes in the RNA helically aggregate with partial pi-stacking along outside of double stranded helical backbone.
多个芘修饰的RNA双链体呈现芘激基缔合物荧光。随着芘掺入数量的增加,芘激基缔合物荧光显著增强。RNA中的芘沿着双链螺旋主链外侧通过部分π-堆积呈螺旋状聚集。
